> So its basically arrogance mixed with an inability to manage their time correctly. I think you are being too harsh. This idea has existed for a long time as a hypothetical way to reduce spam: make the sender pay for postage. The charity aspect is simply a feel-better way to require postage. A cryptocurrency that simply burnt up would also work (but be wasteful to the environment). This would not be used for a primary private personal email account. It would be used for a public email account used by, for example, an open source developer. It would keep signal high and spam low. The real problem I see is that senders, after paying a dollar or two and spending time going through a payment gateway, are going to feel entitled to a response and may get angry when they don't get their money's worth.
